Description

Technical Field

[0001] This utility model relates to the technical field of landscaping machinery, and in particular to a rapid grass-laying device for landscaping projects. Background Technology

[0002] The rapid turf laying device for greening projects is a mechanized or semi-automated equipment used to replace traditional manual turf laying. Its core purpose is to quickly, evenly, and efficiently lay rolls of turf onto the target ground and complete necessary preliminary fixation processes (such as pressing and watering) to improve laying efficiency, ensure laying quality, and reduce labor intensity.

[0003] In related technologies, existing rapid turf laying devices for landscaping projects typically employ a simple mechanical structure consisting of a support frame, unwinding rollers, a fixed guide plate, and a single fixed pressing roller. In actual use, the fixed pressing roller cannot effectively compact the seams between adjacent turf rolls, resulting in uneven seams and turf that is prone to lifting, severely impacting the laying quality and the aesthetics of the lawn. Furthermore, the lack of an integrated moisture retention system means that only surface watering after laying is possible; the back of the turf (root soil) cannot be moistened during the laying process, leading to uneven moisture replenishment. Simultaneously, the turf gradually loses moisture during laying, delaying recovery and resulting in a decline in the quality of the turf laying. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a rapid grass laying device for greening projects, which integrates the functions of unrolling, guiding, humidifying, laying and pressing. The double pressure roller structure improves the pressing effect of turf laying and joints, enhances the laying quality and aesthetics, and sprays water mist on both sides in real time to keep it moist and improve the survival rate.

[0006] To achieve the above objectives, this utility model proposes a rapid grass-laying device for greening projects, comprising a supporting shell, a spraying mechanism, a movable laying mechanism, and a load-bearing and unloading mechanism. The load-bearing and unloading mechanism is mounted on the supporting shell, and the spraying mechanism is mounted on the supporting shell but located away from the load-bearing and unloading mechanism. The movable laying mechanism includes a first pressing roller, a first driving device, two symmetrically arranged support rods, and an adjustable pressing assembly. The two symmetrically arranged support rods are mounted on the movable laying mechanism and located below it. The first pressing roller is rotatably connected between the two symmetrically arranged support rods via the first driving device. The adjustable pressing assembly is mounted on the movable laying mechanism but located away from the first pressing roller.

[0007] In addition, the rapid grass-laying device for greening projects proposed above according to this utility model may also have the following additional technical features: Specifically, the adjustable pressing assembly includes two symmetrically arranged second driving devices, a connecting rod, and two symmetrically arranged second pressing rollers. The connecting rod is movably connected to the spraying mechanism via the two symmetrically arranged second driving devices, and the two symmetrically arranged second pressing rollers are rotatably connected to both ends of the connecting rod.

[0008] Specifically, the spraying mechanism includes a support base, a third drive device, and two sets of symmetrically arranged spray heads. The support housing is hollow inside. The support base is located below the support housing and is connected to the support housing. It is also connected to two symmetrically arranged support rods and two symmetrically arranged second drive devices. The two sets of symmetrically arranged spray heads are located on opposite inner walls of the support housing. The third drive device is located on the support base.

[0009] Specifically, the material feeding mechanism includes a support frame and two symmetrically arranged support rollers, wherein the support frame is disposed on the support housing, and the two symmetrically arranged support rollers are rotatably connected to the support frame.

[0010] Specifically, the support base has two symmetrically arranged guide rollers internally rotatably connected.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: The rapid turf laying device for greening projects of this utility model uses a rolling feeding mechanism to feed the turf in sequence through the support shell and support base, and around the first pressing roller. During the forward movement of the device, the active pressing of the first pressing roller, combined with the independently adjustable height of the second pressing roller, achieves double pressure on the turf, improving the laying quality and aesthetics. At the same time, when the turf is transported inside the support shell, two sets of symmetrically arranged spray heads spray water mist on both sides of the turf, which immediately moisturizes the turf, evenly replenishes moisture, and improves the survival rate.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following description, in conjunction with the accompanying drawings, describes a rapid grass-laying device for landscaping projects according to an embodiment of this utility model.

[0017] like Figures 1-4 As shown, the rapid grass-laying device for greening projects according to this utility model embodiment may include a support shell 1, a spraying mechanism 2, a mobile laying mechanism 3, and a load-bearing material-discharging mechanism 4.

[0018] The material feeding mechanism 4 is mounted on the support housing 1, and the spraying mechanism 2 is mounted on the support housing 1 and is located far away from the material feeding mechanism 4.

[0019] It should be noted that the support housing 1 described in this embodiment can stably support the spraying mechanism 2 and the load-bearing feeding mechanism 4, and realize the movement of the device and the laying of turf through the moving laying mechanism 3.

[0020] The mobile laying mechanism 3 includes a first pressing roller 31, a first driving device 32, two symmetrically arranged support rods 33, and an adjustable pressing assembly 34.

[0021] Two symmetrically arranged support rods 33 are mounted on the movable laying mechanism 3 and located below the movable laying mechanism 3. The first pressing roller 31 is rotatably connected between the two symmetrically arranged support rods 33 through the first driving device 32. The adjustable pressing assembly 34 is mounted on the movable laying mechanism 3 and is located away from the first pressing roller 31.

[0022] It should be noted that the first driving device 32 proposed in the above embodiment adopts a rotary motor. The output end of the rotary motor drives the first pressing roller 31 to rotate. By rubbing against the grass surface of the turf, the rolled turf is unfolded and laid on the ground with pressure. The adjustable pressing component 34 presses the laid turf a second time, and presses the joints of adjacent turf to improve the quality of turf laying.

[0023] Specifically, during the actual turf laying process, the relevant workers place the rolled turf inside the support frame 41 and rotate it using two symmetrically arranged support rollers 42. In the initial state, the third drive device 22 is connected to an external water pipe, which is connected to an external water storage tank (not shown in the figure). The second drive device 341 is in a retracted state, and the second pressing roller 343 and the first pressing roller 31 are parallel to each other with the ground as the reference. The front end of the turf passes through the two symmetrically arranged support rollers 42, the inside of the support housing 1, and the two guide rollers 211 in the support base 21 in sequence. It then turns around the top of the first pressing roller 31, circles back along the outer circumference of the first pressing roller 31, and lays the soil surface on the ground.

[0024] During installation, the first drive device 32 drives the first pressing roller 31 to rotate. At the same time, the operator pushes the device with the handle, and the first pressing roller 31 moves forward and comes into contact with the lawn through friction, so that the soil side of the lawn is laid down and pressed. Meanwhile, the rolled turf in the support frame 41 continuously rolls out material. After the first pressing roller 31 presses, the second pressing roller 343 behind it is used for secondary pressing of the joint after the adjacent turf is laid. The two second drive devices 341 can adjust the distance between the two second pressing rollers 343 and the support base 21, and adjust the overall tilt angle of the device to facilitate the movement of the device during uphill and downhill slopes.

[0025] During humidification, the turf inside the support housing 1 is humidified by water mist sprayed from the symmetrically arranged spray heads 23 inside the support housing 1. The output end of the third drive device 22 pumps external water to the support base 21 and pressurizes the inside of the support housing 1, spraying water mist from the spray heads 23 to achieve humidification of both sides of the turf.

[0026] The device facilitates edge trimming by operators during the initial or final laying of turf, with a cutting space at the bottom of the support 21 to align the turf cutting position with the edge of the space.

[0027] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the adjustable pressing assembly 34 includes two symmetrically arranged second drive devices 341, a connecting rod 342, and two symmetrically arranged second pressing rollers 343.

[0028] The connecting rod 342 is movably connected to the spraying mechanism 2 via two symmetrically arranged second drive devices 341, and two symmetrically arranged second pressing rollers 343 are rotatably connected to both ends of the connecting rod 342.

[0029] It should be noted that, in the above embodiments, the second driving device 341 is a cylinder, which drives the connecting rod 342 and two symmetrically arranged second pressing rollers 343 to rise and fall, and pushes the support base 21, support housing 1 and support frame 41 relative to the ground to tilt, which is convenient for cutting and pushing when going up and down slopes.

[0030] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the spraying mechanism 2 includes a support base 21, a third drive device 22, and two sets of symmetrically arranged spray heads 23.

[0031] The support housing 1 is hollow inside. The support base 21 is located below the support housing 1 and is connected to the support housing 1. It is connected to two symmetrically arranged support rods 33 and two symmetrically arranged second drive devices 341 respectively. Two sets of symmetrically arranged spray heads 23 are located on the opposite inner walls of the support housing 1. The third drive device 22 is located on the support base 21.

[0032] It should be noted that the third driving device 22 described in this embodiment is a water pump. The input end of the water pump is connected to a water storage tank through a water pipe, and external water is pumped to the support base 21 and pressurized in the support housing 1. Water mist is sprayed out through the opposite spray head 23 to moisten both sides of the turf and increase the turf's moisture effect.

[0033] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the feeding mechanism 4 includes a support frame 41 and two symmetrically arranged support rollers 42.

[0034] The support frame 41 is mounted on the support housing 1, and two symmetrically arranged support rollers 42 are rotatably connected to the support frame 41.

[0035] It should be noted that the two symmetrically arranged support rollers 42 described in this embodiment are spaced apart by a distance greater than the thickness of the turf, in order to avoid interference with the rolling turf.

[0036] In one embodiment of this utility model, such as Figure 3 and Figure 4As shown, the support base 21 has two symmetrically arranged guide rollers 211 internally rotatably connected.

[0037] It should be noted that the surface of the guide roller 211 described in this embodiment is provided with protrusions, and the two symmetrically arranged guide rollers 211 rotate in opposite directions to increase the friction with the turf.

[0038] In summary, the rapid turf laying device for greening projects according to this utility model integrates the functions of unwinding, guiding, humidifying, laying and pressing. The double pressure roller structure improves the pressing effect of turf laying and joints, thereby improving the laying quality and aesthetics. It also sprays water mist on both sides in real time to keep the turf moist and improve the survival rate.
